How did NASA help to uncover the adaptations that are made due to living in extreme environments? By analyzing changes in one twin on Earth and the other in space.
By introducing animals and other organisms that could be studied in space.
By running experiments on astronauts that were in space for over a year
By observing changes in retired astronauts over a period of ten years.

I took this at flvsa lol

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
